Two shaft shredder is heavy‑duty size‑reduction industrial equipment. It breaks bulk waste materials into uniform smaller pieces through shearing, tearing and squeezing force from rotating cutter shafts.
It is widely used in waste recycling, construction waste disposal, scrap metal processing, biomass treatment and waste‑to‑energy industries.
The two shaft shredder is designed for materials that are thick, tough, and difficult to process – electronic waste, plastic drums, metal scraps, wood pallets, rubber tires, and even large film rolls. Unlike single-shaft models, the dual-shaft design provides automatic feeding through intermeshing cutters, reducing jams and increasing throughput.
2. Low Speed, High Torque – No Jamming, No Burning
Operating at low rotational speed with high torque, the double shaft crusher generates immense shearing force without overheating the material. This prevents the blades from seizing and reduces fire risks – critical for processing flammable materials like rubber and plastics.
3. Durable Blades – Long Service Life
Blades are made from special alloy tool steels – 9CrSi, Cr12MoV, or SKD-11. 9CrSi offers high hardness and wear resistance for softer materials (rubber, fiber, paper). Cr12MoV and SKD-11 provide superior impact resistance and toughness – ideal for wood, furniture scraps, and hard plastics. Blade life varies by material: for tires, they can last 3-4 years.
4. PLC Control with Overload Protection
The two shaft shredder features an advanced PLC control system. It includes start, stop, reverse, and automatic overload reversal – when oversized or excessive material enters, the system reverses to clear the jam, then resumes automatically. This protects the machine and minimizes downtime.
5. Low Noise and Dust – Environmentally Compliant
With low-speed operation and enclosed cutting chambers, the machine generates significantly less noise and dust than hammer mills or high-speed grinders. This helps you meet local environmental regulations and creates a safer, more comfortable work environment.
6. Easy Maintenance – Replaceable Wear Parts
The cutting chamber is built with heavy-duty plates and easily accessible components. Blades, spacers, and counter-knives can be replaced without dismantling the entire machine. We provide a detailed maintenance manual with every purchase.
Industrial waste recycling – scrap plastics, purgings, sprues, and reject parts
Wood processing – pallets, lumber offcuts, furniture waste, and tree branches
Tire recycling – passenger car and truck tires (preshredding before granulation)
E-waste recovery – circuit boards, cables, and electronic housings
Paper and cardboard – hardboard, corrugated boxes, and document destruction
Metal scrap – light gauge steel, aluminum profiles, and containers
Medical waste – syringes, IV bags, and packaging (with appropriate sterilization)
Municipal solid waste – bulky items, mattresses, carpets, and construction debris
The two shaft shredder is the backbone of any recycling line – reducing volume for transport, preparing material for further grinding, or producing a consistent feedstock for incineration or pyrolysis.
How to Select the Right Dual Shaft Shredder for Sale?
Follow this simple 4-step guide:
Identify your material – Soft materials (rubber, paper, fiber) can use 9CrSi blades; hard materials (wood, hard plastics, metal) need Cr12MoV or SKD-11.
Estimate your throughput – Choose capacity from the table. For 0.5 T/H, YG-600 is sufficient. For 15 T/H, choose YG-2000 with the largest knife option.
Check your power supply – The two shaft shredder runs on electric motors. If you need diesel power, we can customize – confirm with our technical team.
Consider customization – Blade size and output particle size can be customized to your exact requirements. Just tell us your desired final dimension.
